The “CMap Resources” open source project includes all CMap resources for all character collections, which are also referred to ROSes (which is an abbreviation for the three elements of the /CIDSystemInfo dictionary, the first two of which are used to establish compatibility between CMap and CIDFont resources: /Registry, /Ordering, and / Supplement). As of right now, the CMap resources for Adobe-CNS1-6 (released on 09/24/2009 to add support for Hong Kong SCS-2008 by including 68 new glyphs), Adobe-GB1-5, Adobe-Identity-0, Adobe- Japan1-6, Adobe-Japan2-0 (deprecated), and Adobe-Korea1-2 are included.
If you use CMap resources for your work, whether it is open source or not, the “CMap Resources” open source project is now the official home for all of Adobe’s CMap resources.
